Ex Machina Gravity and Terra Monitoring system

The Ex Machina Soundworks Terra + Gravity system is a unified 2.2 professional monitoring solution that merges the three‑way Terra coaxial monitors with dedicated Gravity subwoofers, delivering ±1.5 dB accuracy from 30 Hz to 30 kHz, ±15° phase coherence, zero‑phase LR4 crossovers, integrated Hypex NcoreX amplification and OTA firmware updates, all housed in aerospace‑grade aluminium cabinets.

Overview

Ex Machina engineers the Terra + Gravity system as a single, purpose‑built monitoring platform. The Terra monitors provide a true point‑source image with 90° × 90° conical coverage, while the Gravity subwoofers extend low‑frequency response to a linear 30 Hz (F6 at 20 Hz). By sharing rear‑panel amplification and coordinated DSP, the system eliminates external bass‑management gear and guarantees perfect time alignment across all four drivers.

Technical Highlights

Each Terra unit incorporates an 18 cm coaxial mid/tweeter paired with an 18 cm PuriFi woofer, driven by an ADSP‑21569 SHARC+ DSP and an ESP32 co‑processor. The Gravity subwoofers feature 26 cm PuriFi drivers. Zero‑phase LR4 digital crossovers sit at 200 Hz, 2 kHz for the monitors and 80 Hz for the subwoofers, removing time‑domain smearing and preserving transients. Integrated Hypex NcoreX amplification powers every driver, while pure‑monitoring DSP linearises the speakers themselves rather than correcting the room.

It is a unified 2.2 professional monitoring solution that combines the three‑way Terra coaxial monitors with dedicated Gravity subwoofers, delivering ±1.5 dB accuracy from 30 Hz to 30 kHz, ±15° phase coherence, zero‑phase LR4 crossovers, integrated Hypex NcoreX amplification and OTA firmware updates, all housed in aerospace‑grade aluminium cabinets.

Terra – Three‑Way Coaxial Studio Monitor

The Terra monitor employs an 18 cm coaxial mid/tweeter paired with an 18 cm PuriFi woofer, driven by an ADSP‑21569 SHARC+ DSP and an ESP32 co‑processor. Zero‑phase LR4 digital crossovers sit at 200 Hz and 2 kHz, eliminating time‑domain smearing and preserving transients. Integrated Hypex NcoreX amplification provides clean power, while the monocoque aluminium cabinet remains acoustically inert, preventing resonance and colouration. Each driver is measured and calibrated individually before shipping, ensuring a flat ±1.5 dB response from 40 Hz to 30 kHz, ±15° phase consistency and 90° × 90° conical coverage that yields a wide, stable sweet spot. OTA Wi‑Fi updates continuously refine the measurement models, keeping the monitor at the forefront of accuracy.

Gravity – Dedicated Subwoofer Pair

The Gravity subwoofers complement the Terra monitors with 26 cm PuriFi drivers that extend the system’s low‑frequency response to a linear 30 Hz (F6 at 20 Hz). They receive power directly from the Terra rear‑panel amplification, removing the need for external amplifiers or bass‑management processors. Zero‑phase LR4 crossovers at 80 Hz integrate the subs seamlessly with the monitors, preserving phase coherence and delivering precise stereo bass. Like the monitors, each subwoofer undergoes individual driver‑level calibration and benefits from OTA firmware updates, ensuring consistent performance as the system evolves.

System Integration & Calibration

Ex Machina measures and calibrates each driver individually before shipment, then stores the data in the onboard DSP. OTA Wi‑Fi updates continuously refine the measurement models, ensuring the system improves over time without additional hardware. The shared DSP architecture synchronises phase and level across the monitors and subwoofers, delivering seamless stereo bass and full‑range accuracy in any acoustic environment.
